The seeds of Elymus tangutorum infected with Epichloë bromicola were treated by soaked, wet-dry cycle, mechanical damage, and fungicide. The germination time and germination rate the seeds were measured. The results showed that each treatment had a certain effect on the germination of E. tangutorum infected with Ep. bromicola seeds. The total germination rate: wet-dry cycle (soaked for 6h, dried for 6h)> mechanical damage> fungicide (cyclosporin T) immersion (6h)> aseptic water soaked (6h)> CK can be seen from the experimental data. And wet-dry cycle, aseptic water soaked, and mechanical damage have significant effect on increasing the rate of seeds. Among these methods, the germination rate of the seeds treated by wet-dry cycle method was the highest. The treatment has both chemical and physiological functions, thus improving the germination rate and propagation coefficient of seeds.
